Ignition Time Delay In Swirling Supersonic Flow Combustion

open access: yes, 2012
Supersonic hydrogen-air cylindrical mixing layer is numerically analyzed to investigate the effect of inlet swirl on ignition time delay in scramjets. Combustion is treated using detail chemical kinetics. One-equation turbulence model of Spalart and Allmaras is chosen to study the problem and advection upstream splitting method is used as computational

IGNITION DELAY TIME INVESTIGATION OF GTL FUEL BLENDS

open access: yes, 2022
Ignition delay is a vital combustion characteristic of any fuel that directly affects the development of internal combustion engines (ICEs) and exhaust emissions, especially in diesel engines. Considering the global interest in alternative fuels, GTL (Gas to Liquid) can be considered one of the promising new alternative fuels, especially for ...

Numerical simulation of ignition delay time for petroleum and renewable fuels

Fuel, 2021
Abstract In this research, the composition and proportion of surrogates were first determined according to the composition of the petrochemical and renewable fuels. Then, the CHBR model in CHEMKIN-Pro software was used to verify the ignition delay time of HRJ, JP-5, and HRD. The differences in the ignition delay time of the fuels under an equivalence
